Osteospermum plant named ‘Osjamvan’

ABSTRACT

A new  Osteospermum  plant particularly distinguished by its compact plant habit, good flower quality and vanilla colored flowers.

Latin name of the genus and species of the plant claimed: Osteospermum ecklonis.

Varietal denomination: ‘Osjamvan’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis.

The new Osteospermum is propagated by cuttings resulting from an open pollinated population from a proprietary Osteospermum ecklonis seedling selection as the female, or seed, parent identified as breeder's code ‘E0053-1’ (unpatented). Breeder's code of new plant is ‘F0216-2.’

The new Osteospermum was discovered and selected as a single flowering plant within the progeny of the stated population grown in Enkhuizen, Netherlands, in 2001. The new Osteospermum plant has been repeatably asexually reproduced by cuttings in Enkhuizen, Netherlands over a period of 5 years. The new variety is stable and reproduces true to type in successive generations of asexual reproduction.

DESCRIPTION OF THE DRAWING

This new Osteospermum plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Osteospermum plant. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 28 week old plants. The instant plant was grown indoors in a 10.5 cm container and transplanted into the open field in week 20.

Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London, edition 2001.

Plants of the cultivar ‘Osjamvan’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, day length, and fertility level without, however, any variance in genotype.

Plants of the new Osteospermum differ primarily from the plants of the female parent ‘E0053-1’ in the following characteristics:

Plants of the new Osteospermum have bigger flowers, broader ray florets, and are more floriferous throughout the summer than plants of the female parent ‘E0053-1’.
